Normally distributed continuous variables were expressed as the mean ± SD and compared using the Student’s t test. Non-normally

distributed continuous variables were expressed as the median (interquartile range) and compared using the Mann–Whitney U test. Categorical variables were expressed as numbers (proportions) and analyzed PD0332991 supplier using the chi-squared test or Fisher’s exact test. The trend for each value was analyzed using the Jonckheere−Terpstra [26] test. All probability values were 2-tailed and all confidence intervals were computed at the 95 % level. Results Patient characteristics In this study,

we enrolled 50 IgAN patients with complete or partial clinical remission after TSP. The basic characteristics of the enrolled patients (N = 50) whose clinical parameters could be collected are summarized in Table 1. The study population included 40 % males with a median age of 37 years. The average CCr and LY2109761 manufacturer urinary protein excretion levels were 98.2 ml/min and 0.54 g/day, respectively. A total of 52 % of the patients had complete clinical remission after TSP.
